Real roots implies that the value of the root will be greater than or equal to zero. \n" ); document.write( "ie. say the root is x,then x>=0 \n" ); document.write( " \n" ); document.write( "As per the question,one of the three roots is -2/3 \n" ); document.write( "if all three roots are real,then (-2/3) cannot be one of the roots. \n" ); document.write( " \n" ); document.write( "Please check your question and post again. \n" ); document.write( "-Prabhat\r \n" ); document.write( "\n" ); document.write( "[Edit: The three roots (whether real or not) can be found by equating p(x) to zero and then solving the trinomial ] \n" ); document.write( " |
